Description

TECHNICAL FIELD

[0001] The utility model relates to vehicle detection technical field, concretely relates to a flat plate type motorcycle brake test bench of all vehicle types. BACKGROUND

[0002] The main role of motorcycle brake test bench is to simulate the braking situation on the real road, and the performance of motorcycle braking system is evaluated by measuring parameters such as braking force and braking distance. Since the performance of motorcycle braking system is directly related to the safety of the passengers, it is particularly important to use motorcycle brake test bench for regular detection and evaluation.

[0003] At present, the commonly used is the drum counterforce type brake test bench, which adopts motor drive force drum to generate friction with the measured wheel, and realizes the wheel braking force by measuring the friction force through the sensor. Figure 3 As shown in the figure, the mechanical part of the motorcycle brake test bench is composed of tension and compression sensor 101, motor 102, bearing seat 103, driven drum 104, chain 105, driving drum 106, rack 107, speed reducer 108 and counterforce type lever arm 109, and its measurement principle is as follows: when detecting the vehicle, the motor rotates to drive the wheel supported on the two drums to rotate at low speed, and when the tested wheel brakes, a braking force is applied to the drum to prevent its rotation, which is transmitted to the force sensor 101 through the drum-drum shaft-motor speed reducer-counterforce type lever arm, the sensor converts the force signal into voltage signal and sends it to the instrument, and the instrument displays the braking force in digital form after a series of processing. The main shortcomings of the current equipment are that it cannot be suitable for various different specifications and models of motorcycles, especially three-wheeled motorcycles.

[0004] The remaining motorcycle brake test benches also have the following technical problems:

[0005] 1. Due to the mechanical mechanism limitation of the drum type brake test bench, the left and right drums are arranged on the same axis, which limits the measurement of the side wheels of three-wheeled vehicles and the main wheels on the same axis, and the vehicle cannot be effectively measured if it is not on the same axis.

[0006] 2. Due to the use of counterforce measurement, the drum exerts a large backward force on the wheel during braking detection, which may cause the vehicle itself to be unable to be fixed, and a clamping table is needed to fix the other wheels of the tested wheel. Since the installation of the clamping table needs to be higher than the ground and has a certain width, it is limited to measure only the positive three-wheeled motorcycles with wheel spacing greater than a certain value (depending on the spacing between the two clamping tables) and the side three-wheeled motorcycles with wheel spacing greater than the value; it is also limited that the width of the motorcycle tire should not be greater than a certain value (the value depends on the spacing between the two clamping tables).

[0007] 3. The roller reaction force brake test bench cannot test three-wheeled motorcycles, three-wheeled motorcycles with a wheelbase smaller than the width of the clamping platform, motorcycles with a tire width greater than the distance between the clamping platforms, and sidecar motorcycles where the side wheels are not on the same axle as the rear wheels of the main vehicle.

[0008] Therefore, this utility model proposes a brand-new flat plate brake test bench to solve the testing of various types of motorcycles with different wheels, wheelbases, and styles and models, including two-wheeled, sidecar, three-wheeled, and reverse-car motorcycles. Utility Model Content

The first braking test unit and the second braking test unit are placed side by side, and the third braking test unit and the fourth braking test unit are placed side by side. The two sets of side-by-side braking test units are arranged with a fixed distance between them to form an irregular four-plate type braking test bench.

[0012] Furthermore, each of the braking test units includes a base plate, a pressure sensor, a braking platform, a steel ball, and a tension sensor; wherein, the base plate is provided with a braking platform, the base plate and the braking platform are equipped with a pressure sensor, a steel ball is provided between the pressure sensor and the platform, and the front end of the braking platform is fixedly connected to the tension sensor.

[0013] Furthermore, each of the braking test units has a length of L, a width of D, and a left-right spacing of W. The width of the misalignment between two sets of parallel braking test units is D / 2, and the gap is 25mm.

[0014] Furthermore, the braking platform is at the same level as the ground outside the pit.

[0015] Furthermore, the types of motorcycles include two-wheeled motorcycles, three-wheeled motorcycles, reverse three-wheeled motorcycles, sidecar motorcycles, four-wheeled motorcycles, and other types of motorcycles.

[0016] Based on the above technical scheme, the utility model embodiment can produce at least following technical effects:

[0017] (1) the utility model discloses a flat plate type motorcycle brake test bench of all vehicle types, uses flat plate type brake test bench to detect motorcycle, and the past flat plate is mostly used to detect automobile, arranges four plates in specific relative position, can make different motorcycles stop on the brake sampling plate when detecting, ensures the normal sampling, can satisfy the requirement of various parameters, and the plate structure, size and relative empty position of flat plate brake test bench have special size design, guarantee to satisfy all vehicle types.
